The manner in which the above described means represented in Figs. l and l" operatcs isknown. character electro-magnet 25 is-selected by a perforated symbol of the hand consisting ot two holes.

Above the bar 5l there vare arranged three scescrews 54, 55 and 56', of which the screws 54 and 56 are formed as contacts. Below the bar or lever 5l there are arranged .two set-screws 57 120 and 58. lhe'former is likewise a contact and is electrically cormected .with thescrewA 54.. The screws 55 and 58 are only used as stops or set-screws. About in the centerj between the screws 54Zand 55 a s rin'g59 is 125 attached to the lever .5l and ten to pull' it upward.'

When the`armature65 is attracted by the electro magnet 66the connection between the contact screw 54 and the lever 51 is interrupted.I Inorder to avoid the circuit in which the 4electromagnet 66 is connected being inter` `rupted prematurely, the `'screw 57 is also used as a contact screw and connected with4 `the screw54. fNow when thelmain circuit is closed again the lever 51" lirst lies a "the screw 57 and is only then with rawn fromthe screw 54 ntthe left-hand end.

The latter eleotromagnet is operated :nl soon-:1S :i perforated symbol Z: Z acts on the two switch4 levers ik and 41 after the circuit has previously been broken by the. switch lever 14..

AS alreadystated abo-ve, 'the switch lever 18 Serves for canceling lines and the switch lever 14 for canceling Words. 1n order to return the switoh lever 18 into the 'circuit closing position, the perforated symbol i Z is used which servesL as symbol for the encl of u. line when the register banolis'operatecl normally. In likernanner'the perforated Symbol Z' Z serves forwitching in the lever 14, which symbolsev otherwise forsetting the member for the spcbetween two Words. As soon ,as one of the switch levers 14 and 18 has been brought into the cut-out' or caneeling position, in consequence ofthe conductor 9 being separated from the Source of current, the perforated Symbols i Z and 7c Z and with them the character eleetromagnets 25H :intl 25M can not aetnormally.

the resistance 76 to theI conductor 74. F 01' (loing @Way with the notionof the perforated 'net 77 and the resistance 76 are so proportioned that, in consequencer of the current being weakened, the vcharacter electromagnets 25 cannot act. But the electromagnet 77 is so sensitive, in consequence of its winding of fine wire, however, that it. is-suli ciently energized bythe weakened current in order to be able to attract its armature' 82.

Now if anyperforated symbol of the per-V forated -bandvacts on the switches 4 to 4:1 after the bar 7 2j has been released from the catch 81 by the magnet 80, the electromagnet 77 is operated and pulls the lever 72 down. The latter first lies, as above described, against thecontact 79, is caught by the catch 81, and lastlyv lies against the contact 73. The latter event only happens when the electromagnet 77 ,has ceased to act.` :In this manner each individual perforated symbol can be made inoperative by a preceding sym bol which acts on lthe elect-romagnet 8O.

The above described switching means can be used in various ways. The register band can be passed through the type-setting machine bothin the direction in which Vthe band is made and also in the opposite direction. In the above description it has been supposed that Athe register band runs through the type-setting machine in the opposite direction to that in which the band isV reduced, and that consequently those sym- '01s, which are perforated after the sections which are to be canceled, become operativel in the type-setting machine before these sections, as -is at jonce understood. :if it is wished to pass the register band through the type-setting machine in the direction in which the band is made, which is preferable under certain circumstances, it must be otherwise arranged that the operation ot the band is stopped opportunely 4at the defective places. For this purpose the register bands may besubjected in known manner to a special process in. which the symbols,

` which are perforated according to the groups of holes which are to be canceled,

automaticall b'ringabout the perforation 6o of'new sym cls-which arein front of the groups of holes whichare to be canceled.

he only"ques tion here iswhich canceling .and inserting symbolsfare tobe used in the two cases, ,and honI these are` `to act on `the described -Xtclring mea-ns; A change of `brought about.

the switching means in itselr is only necessary to the extentthat the electromagnet 25.

7c l, which according to the above should be used for setting the symbols for the separation of words, must be omitted, so that the symbols for the spaces tween two words have to be set by' any otherl f character electromagnet 25. Consequently there is one character electromagnet less at' disposal. As the symbol for the space bef' tween two words there must then belemployed a symbol which consists of the hole b and one of the holes c tok. If a' word has been perforated incorrectly and is to be canceled, the perforated symbol c Z is punched behind the word. In the intermediate process to which the band is subjected this latter symbol has to cause a hole a to be added to y the symbol for the space between two words which is in front of the defective word. It for example as symbolk for the space between two words 'the symbol b e is used, the l defective word is lastly between the symbols a b e and 7c Z. At the symbol a b c the fpllowing occurs: In consequence ot' theaction of the hole e the switch 4 is first closed and the switch lever 20a is reversed tofjthe contact 21. 4The following circuit is-'made through the hole ofthe symbol; From the battery 1, by way of conductor 5b, switch lever 20 contact 21,1, conductor 29- to the electromagnet 25,1, and. on to the conductor 9 and sourcepo'it current 1. Consequently the electromagnct 25M, is energized and cuts oit the current by means of the lever 14. The

sign h c cannot operate simultaneously, be

cause the character electromagnet 25{, remams without current 1n consequence of the separation of the contact lever 2()n from the contact 22EL and the conductor 10b. Behind the group of holes which is to be'canceled there is the symbol hl'pwhich acts on the electromagnet 31 in the `-'manner which has already been described.' Y

Thf-switching device represented in Figs. 2 to 4 has the special pcculiarity `that the cut-out and cutfin m'agnets'- only cui` themselves out of circuit by their operation when the intended action is completely which could have as a consequence arhescillation ofthe armature and tinaiiy the arma ture remaining in ay wrong position. Further, the insertion in circuit takes place without'the coperation of the type-setting machine and without a pause 'in the moren ment of the band. For this rcasontbe means are suitable particularly for Ihi h speed type-setting machines in whichjt 'e band machine but continuously.
